Answer:

Hold the CPU fan so that it won't spin and blow this with compressed air.

Explanation:

While cleaning the computer system from the inner side then we have to follow some steps.

  • Firstly, shut down the system properly and remove it from the power supply.
  • Then, open the cabinet of the computer system.
  • Then, clean the internal parts of the system through simple air pressure and hold the CPU fan during that time to avoid spinning.
  • Clear the dirt layer using the can of compressed air over the cabinet fans.

Sales management wants a small subset of users with different profiles and roles to be able to view all data for compliance purp
Lapatulllka [165]

Answer:

Last Option is correct answer. ( Option D)

Explanation:

Option A is rejected because this will allow the view permission but as mentioned the management want a new profile for the users as well.

Option B is rejected because again it will not facilitate the different profile requirement.

Option C is not answer because It will only help in viewing the data and granting permission.

Option D is selected because it will meet both requirements which are to make a new profile first of all and then grant the View permissions to these profiles for the user subset.

Aleksandr [31]

Answer:

Explanation:

1. Write a program that declares an array named alpha with 50 components of the type double. Initialize the array so that the first 25 components are equal to the square of the counter (or index) variable and the last 25 components are equal to three times the index variable.  

  double alpha[50];

   for (int i=0;i<25;i++)

   {

       alpha[i]=i*i;

       alpha[i+25]=(i+25)*3;

  }

2. Output the array so that exactly ten elements per line are printed.  

   for (int i=0;i<50;i++)

   {

       cout<<i+1<<". "<<alpha[i]<<" ";

       if (((i+1)%10)==0)

       {

           cout<<endl;

       }

   }

3. Run your program again, but this time change the code so that the array is filled with random numbers between 1 and 100.  

   double alpha[50];

   for (int i=0;i<50;i++)

   {

       alpha[i]=rand()%101;

   }

   for (int i=0;i<50;i++)

   {

       cout<<i+1<<". "<<alpha[i]<<" ";

       if (((i+1)%10)==0)

       {

           cout<<endl;

       }

   }

4. Write the code that computes and prints the average of elements of the array.  

   double alpha[50],temp=0;

   for (int i=0;i<50;i++)

   {

       alpha[i]=rand()%101;

       temp+=alpha[i];

   }

   cout<<"Average :"<<(temp/50);

5. Write the code that that prints out how many of the elements are EXACTLY equal to 100.

   double alpha[50],temp=0;

   for (int i=0;i<50;i++)

   {

       alpha[i]=rand()%101;

       if(alpha[i]==100)

       {

           temp++;

       }

   }

   cout<<"Elements Exacctly 100 :"<<temp;

Please note:  If you put  each of above code to the place below comment  it will run perfectly after compiling

#include <iostream>

using namespace std;

int main()

{

   // If you put  each of above code here it will run perfectly after compiling

   return 0;

}
